If you make an electromagnet using a battery circuit and a steel nail, how can you increase its magnetic strength?
Use a longer nail.
Wrap more coils of wire around the nail.
Replace the nail with a copper rod.
Remove the plastic insulation from the wire coil.
I would like a little help with this please,··
